Strengthening System and Implementation Research Capacity for Child Mental Health and Family Well-being in Sub-Saharan Africa

Background Children in Sub-Saharan Africa (SSA) experience high rates of mental health problems, and the region has limited access to mental health resources and research capacity to address the needs. Despite the success of numerous evidence-based interventions (EBIs) and emerging methodology from the field of implementation science for addressing child mental health needs, most EBIs and implementation science methodology have not been applied in SSA contexts. The SMART-Africa Center aims to address these child welfare, mental health, services, and EBI implementation research gaps by establishing a regional trans-disciplinary collaborative center and studying strategies to strengthening mental health system and implementation research capacity. Our paper describes the overall framework and strategies that SMART-Africa team developed to strengthen capacity in three SSA countries (Ghana, Kenya, and Uganda) while focusing on its contextualization for the Kenyan school-community mental health settings. Methods to document the progress and impacts are also described. Methods The design of the system and research strengthening activities is guided by a SMART-Africa Capacity Building framework. Two areas of capacity are focused. Mental health system capacity focuses on building political wills, leadership, transdisciplinary partnership, and stakeholders’ global competency in evidence child mental health policy, intervention, and service implementation research. Implementation research capacity building focuses on building researchers’ implementation research competency by carrying out an EBI implementation research (using a Hybrid Type II effectiveness-implementation). For illustration purpose, we describe how the system strengthening strategies has been applied in Kenya, and how the mixed methods design applied to assess the value and impacts of the capacity building activities. Feedback data and evaluation data collection using qualitative and quantitative methods for both areas of capacity building are still ongoing. Data will be analyzed and compared across countries in 2020–2021. Conclusion Our work has shown some feasibility of applying the theory-guided system strengthening model in improving child mental health service system and research capacity in one of the three SMART-Africa partnering countries. Our mental health landscape and resource mapping in Kenya also illustrated that capacity building in SSA countries involved complex dynamic, history, and some overlap efforts with multiple partnerships, and these are critical to consider in training activity and evaluation design.

of SSA countries have mental health policy or legislation. Most African countries spend less than 3% of government health expenditure on mental health, and most mental health expenditure (average 71%) is consumed by mental hospitals (Huang, Cheng, Gathibandhe, Bauta, & Akena, 2016;WHO, 2018). The funding is much lower than the WHO recommended 15% minimum. (World Health Organization, 2003). With regard to existing mental health systems and services because of low investment, most African countries have a limited number of mental health and social welfare workers, with a ratio of less than 1 per 100 000 population for psychiatrists, nurses, or social workers in most countries, compared to between 10 to 60 in developed countries WHO, 2014a). At a community level, private health care and the educational and social development sectors also only play a limited role in provision of preventive mental health services (Doku, Wusu-Takyi, & Awakame, 2012;Roberts, Mogan, & Asare, 2014). Few NGOs work directly on community mental health and MNS disorders, but a large number provide mental health services as part of other infectious disease and humanitarian programs, such as counseling in HIV programs and trauma-informed care for refugee, violence, or war conflict affected populations (Henry, 2006;Omar et al., 2010;Walsh, Dawson, & Mattingly, 2010). In relation to research, child mental health research is limited because inadequate resources and capacity have been developed or allocated for epidemiological, populationbased surveillance, or mental health intervention research. There are few trained mental health implementation or health/social welfare service researchers to support evidence-based intervention (EBI) adaptation, implementation, and evaluation research . The research funding is also limited, and relies mainly on the priority and funders outsider of the SSA (WHO, 2012(WHO, , 2013.

Emerging Global Strategies to Address Child Mental Health Challenges
To address mental health services, policy, and research gaps in SSA countries, several fameworks and strategies have been developed. For mental health system and service development, WHO has proposed two frameworks. The WHO's Comprehensive Mental Health Action Plan (WHO, 2013) proposes strengthening governance, providing integrated mental health services in communities, implementing strategies for mental health promotion, and strengthening evidence, research, and information systems for mental health. The WHO's Optimal Mix of Mental Health Services Pyramid framework (WHO, 2009) proposes that the majority of mental health service planning should focus on services outside the traditional healthcare delivery system and in communities because of high need and relatively low cost (WHO, 2009(WHO, , 2013. To address intervention research gaps, recent advancement of implementation science in global health, and new emerging evidence for adopting EBIs from developed to developing countries have also provided additional strategies to tackle the enormous mental health needs in children (Huang et al., 2017) . For example, several reviews strongly indicate that EBIs can be effective for children from different cultural backgrounds if adapted appropriately with new implementation science methodology (Baumann et al., 2015;Gardner, Montgomery, & Knerr, 2015). To address policy and research leadership gaps, adult mental health research in LMICs have generated many strategies for mental health leadership development (Abdulmalik et al., collaboration ((AFFIRM, 2013;Breuer et al., 2014;Center for Global Mental Health, 2011;PRIME, 2015). Despite the potential of these system, implementation research, and leadership development strategies, these strategies have not optimally been applied in child mental health intervention and service research in SSA countries.

SMART-Africa Initiate
Center for Strengthening Mental Health Systems and Research Training in Sub-Saharan Africa (SMART-Africa) is a SSA regional research center funded by the US National Institute of Mental Health (NIMH) in 2016. The Center aims to address social welfare and mental health needs of children in SSA by establishing a regional transdisciplinary collaborative to support system strengthening and implementation research capacity building. Guided by the global system, implementation, and leadership strategies described above and emerging lessons informed by literature and in consultation with our SSA partners, the SMART-African Center has developed a capacity building activity framework to guide the system changes across three SSA countries (Kenya, Ghana, Uganda). The goals of this paper are to introduce the guiding framework and strategies of our approach for strengthening child mental health/welfare system and implementation research. For illustrative purposes, we describe how this framework has been applied in Kenya.
In policy Kenya has a mental health plan and legislation developed in early 1990s. Kenyan Mental Health Policy, which provides for a framework on interventions for securing mental health systems reforms, was recently launched and offered key priorities from 2015 to 2030. This is in line with the Constitution of Kenya 2010, Vision 2030, the Kenya Health Policy (2014-2030 and the global commitments (MOH Kenya, 2015). The current policy prioritizes the needs for prevention, and to reduce the prevalence and the impact of mental disorder. It recognizes children and adolescents as one of the vulnerable groups that need for targeted mental health interventions (Atwoli, 2013).
In research, there is inadequate data and information on the prevalence of mental and behavioral disorders in representative national child population in Kenya. Also, child mental health psychopathology or epidemiological research and implementation research is limited  . There are few trained research personnel to support child mental health epidemiology and service research prior to 2015 . Among the published studies that conducted prior to the SMART-Africa initiative, most mental health research has focused on adults and child mental health research was focused on adolescents (Mbwayo & Mathai, 2016) .
In service, child mental health service workforce and system is lacking. Even though social workers are part of the mental health system, they are few and therefore reliance is on lay volunteers who are not always optimally trained or integrated. Up until recently, psychologists were also not part of the formal work force (MOH Kenya, 2015).
Given the weak mental health system and research capacity, several efforts have been made at the regional and national-level in mental health system strengthening in Kenya since 2010. Although most of the earlier efforts focused on adult mental health, the capacity established through these efforts are important to consider in the SMART-Africa partnership. Here, we highlight four areas of such efforts. One, great strides have been made in Kenyan mental health research during the Fogarty International Center's Medical Education in Partnership Initiative (MEPI) (2010-2015) (Monroe-Wise et al., 2014). Under this MEPI initiative, attention was drawn to infectious diseases, maternal and child health, and behavioral change/ mental health in a significant manner. Several of our Kenyan key investigators participated in this Initiative and have benefited from mental health research methodology training and the efforts in strengthening capacity of mental health researchers (including psychiatrists, clinical psychologists and psychiatric/social workers) (NIH Fogarty International Center, 2019). Two, under the WHO Mental Health Action Plan and Mental Health Gap Action Program (mhGAP) Initiatives, which aim to improve mental health outcomes as part of the Sustainable Development Goals (SDGs) (Daar et al., 2014), a number of innovative collaborations occurred globally, especially on the topics related to capacity building of health/mental health specialists and lay and non-specialists. As part of this global workforce development effort, a number of Kenya-UK based collaborations were created to address similar workforce, health systems and financial barriers in mental health integration in Kenya Jenkins et al., 2013;Othieno et al., 2009;Semrau et al., 2016). Some of our Kenyan key research and governmental partners were also part of these initiatives. Three, Kenyan population's mental health needs have long been recognized, and mental health research has been targeted or integrated in many areas of health research. For example, over the past decade, while many health and behavioral health interventions have been tested in Kenya (e.g., HIV/AIDS patient engagement, maternal depression, infant feeding, reproductive health, respectful maternity), many researchers recognized the importance of integrating a mental health component and engaging multilevel stakeholders in health research to achieve greater public health impacts (Kamau, Omigbodun, Bella-Awusah, & Adedokun, 2017;Khasakhala, Ndetei, & Mathai, 2013). Four, since 2015 (similar funding timeframe as the SMART-Africa), Kenya has been a site of interest for many international development agencies for testing novel mental health policy, leadership, cost-effective and locally relevant interventions. For example, a collaboration between University of Nairobi (UON) and the University of Washington (UW), which builds on a 30-year HIV/AIDS research collaboration, has extended previous HIV research to include maternal and child mental health, gender-based violence, and HIV related substance abuse research. A number of our Kenyan collaborators are part of this collaboration, and their partnership has yielded a number of accomplishments that has advanced Kenya's mental health research . Similar efforts have being made in parallel by NIMH funded another U19 PAM-D (Partnership for Mental Health Development in SSA: a collaborative initiative for research and capacity building), which further develops collaboration research around mental health in the SSA region (Gureje et al., 2019).
In sum, a decade of mental health research and capacity building efforts in Kenya highlight the numerous strengths that the Kenyan team bring to SMART-Africa Center. The landscape and resource mapping findings also illustrate how solid mental health research competency/ capacity has already been established in Kenya and which can be transferred to child mental health implementation research. The findings also suggest that mental health partnerships and system strengthening are not new to the Kenyan investigation team, and their ability to develop efficient partnerships based on their prior experiences and lessons learned. Finally, child and adolescent mental health presents with greater challenges than adult mental health research as it requires involvement of several critical implementing partners like teachers, school, child protection and government, non-governmental and community stakeholders (Mbwayo & Mathai, 2016;Mbwayo, Mathai, Harder, Nicodimos, & Vander Stoep, 2019).

Goals of this Paper
The goals of this paper are to introduce the guiding framework and strategies of the SMART-Africa approach for strengthening child mental health/welfare system and implementation research. SMART-Africa is aimed to address service gaps and mental health needs of children in SSA by establishing a regional transdisciplinary collaborative to support system strengthening and implementation research capacity building. Given the child mental health system is underdeveloped, under resourced and limited implementation research has been carried out in Kenya on child mental health, our research offers an opportunity to study the feasibility and impact of the SMART-Africa approach in strengthening SSA countries' child mental health system and implementation research capacity. In this paper, we describe how SMART-Africa framework has been applied in Kenya. We also describe how the mixed methods design is applied to assess the value and impacts of the capacity building activities.

SMART-Africa's Approaches for Strengthening Child Mental Health Capacity
Guiding Frameworks and Strategies.-SMART-Africa aims to promote child mental health and address existing system gaps in SSA countries by developing and studying strategies to strengthen mental health system and implementation research capacity. In line with the WHO recommended frameworks and implementation science training methodology described above, SMART-Africa Administrative Core (from the US) and Capacity Building Leads (from South Africa) developed a capacity building framework ( Figure 1) that would simultaneously strengthen two areas of capacity-child mental health system and implementation research capacity in three SSA countries (Ghana, Uganda, Kenya). As shown in Figure 1, the framework includes two targeted areas of capacity building outcomes (system and research outcomes) and four categories of activities (activities for promoting evidence-based policy and implementation research, scale-up research, technical support, and networking/information sharing) that have suggested in the literature and by WHO as effective strategies to strengthen mental health capacity in SSA.

Service System and Research Strengthening
Activities.-To further map-out activities for two areas of capacity building (system and implementation research), the SMART-Africa US and South Africa leadership team designed a list of activities that are relevant to 4 categories of activities listed in Figure 1. Table 1 detailed the Capacity Building design and activities that are considered for strengthening mental health system and implementation research capacity. In mental health system capacity building, five activities centered on building political will, leadership, trans-discipline partnership teams, and general competency in evidence-based policy, intervention, and service implementation research are focused. Activity design for this area was driven by WHO recommended Comprehensive Mental Health Action and Service Pyramid frameworks (WHO, 2009(WHO, , 2013 and lessons learned from health system strengthening and leadership development program from international projects (Abdulmalik et al., 2014;Center for Global Mental Health, 2011;Koon et al., 2019;Omar et al., 2010;WHO, 2009WHO, , 2013, and effective partnership frameworks (Masseli, Lys, & Schmid, 2005). implementation research capacity building, eight activities centered on strengthening child mental health implementation research capacity and generating new EBI effectivenessimplementation evidence are considered. Hands-on experience in carrying out an EBI (Multiple Family Groups/MFG) implementation project in three country sites is structured. As per our design, the activities listed target all aspects of child mental health system barriers listed above, but actual formats vary by countries.
MFG.-We chose to adapt MFG for use in SSA because: 1) the EBI addresses one of the most common child mental health problems, disruptive behavioral disorders (DBDs), in the SSA region. Estimated prevalence of DBD in SSA and our study countries ranging from 12 to 33% (Apkan, N.C., & E., 2010;Ashenafi, Kebede, Desta, & Alem, 2001;Cortina, Sodha, Fazel, & Ramchandani, 2012;Huang, Bornheimer, Dankyi, & de-Graft Aikins, 2018;Magai et al., 2018;Nakigudde, Bauta, Wolf, & Huang, 2016); 2) it has been tested with children from families experiencing high adversity, stress, and poverty in the US, African, and HIV/ AIDS affected community contexts (Bhana, McKay, Mellins, Petersen, & Bell, 2010;Bhana et al., 2014;Gopalan et al., 2018); and 3) the EBI has shown to be effective in promoting parenting (i.e., family organization, connectedness, support, communication, and discipline practice), improving quality of family life, and reducing child behavioral health challenges (Chacko et al., 2015;Gopalan et al., 2018;Gopalan et al., 2014). Briefly, MFG is a community driven and group-based evidence-based psychoeducational and support program that strengthens families to address child disruptive behavior problems or behavioral challenges. MFG utilizes a flexible implementation approach, which can be delivered by parent peers, community health workers, or social welfare/mental health professionals. It can also be implemented in diverse settings, such as social welfare, community-based organizations, schools. MFG was developed based on a body of evidence regarding the influence of parenting and quality of family life on youth behavioral challenges; and it targets multiple risk factors tied to poverty related stress and parenting. MFG focuses on six core areas of contents (4Rs-2Ss): Rules, Responsibility, Relationships, and Respectful Communication and Stress and Social Support. As families discuss their issues around these areas, children and adult caregivers learn to solve problems together and build each other's capacities. The approach enables the high-risk problem behaviors to be understood and tackled but also provide some common learning around internalizing and externalizing disorders at home (Bhana et al., 2010;Gopalan et al., 2018).
MFG Implementation Research Design.-To strengthen implementation research capacity and generate new effectiveness-implementation evidence in SSA, the same three-arm Hybrid Type II effectiveness-implementation research (Curran, Bauer, Mittman, Pyne, & Stetler, 2012) and Reach-Effectiveness-Adoption-Implementation-Maintenance (RE-AIM) evaluation design (Glasgow, Vogt, & Boles, 1999) are applied to three study countries, and same evaluation tools (with language adaptation) are used for evaluation. Across countries, MFG is tested in school settings using two task-shifting implementation approaches: (i) implemented by community health workers/teams (proposed to be under Ministry of Health structure) and (ii) implemented by school community members (parentpeers or teachers from school communities, to be determined by study countries). The effectiveness findings from these two implementation approaches would be compared with control condition, which receives mental health materials for awareness promotion. Given the differences in research capacities across countries, Uganda would carry out a scale-up research study in 30 schools, and Ghana and Kenya would carry out a small scale (pilot) implementation-effectiveness study in three schools. Detailed descriptions about MFG effectiveness-implementation trial design and evaluation methods/measures can be found in the SMART-Africa Trial article (Ssewamala et al., 2018).
Additional Capacity Building Feature Considered.-In addition to the capacity building activities described above, several additional design features were carefully considered. To support the capacity building activities, SMART-Africa brings rich expertise and resources from multidisciplinary scholarships from both the USA and African regions (South Africa, Ghana, Uganda, Kenya) to support the training. The team of experts from all participating countries have contributed to a range of capacity building activities such as mentorship, technical support, and offering workshop training. We recognize country level variations and each country's strengths, but at the same time recognize local specific needs and local governments' priority differences We allow capacity-building activities or stakeholder meeting discussion topics to vary based on the needs and priorities, and provide technical implementation methodology support or knowledge sharing. We also emphasize strength building, network learning, and SSA local stakeholder collaboration, which recognize each country's unique mental health capacity strengths and experiences, and contribution to the network of knowledge. Our network learning approach draws on existing partnerships in the four countries to create child implementation science "laboratories", which offers the opportunity to experiment both within and across country systems. Furthermore, to create efficient communication and learning opportunities, we utilize distance learning/communication technologies as well as group-and individual-based mentorship support and learning opportunities to share implementation science related knowledge and research skills. The eclectic use of multiple training methods (i.e., webinars, mentorship support), facilitate knowledge sharing and translation of skills to action across SSA countries and between US and SSA countries (O'Neil et al., 2015).
Evaluation.- Table 1 "Methods for Assessing Capacity Building Model" column outlines our indicators of success and methodology applied for evaluation in two capacity building areas. In general, a mixed methods evaluation design is applied. The impact assessment for the System capacity building activities is based on qualitative data (from researchers and stakeholders). For implementation research capacity building outcomes, the primary outcomes will be evaluated based on implementation effectiveness data that apply the same quantitative measures used in the scale-up study site-Uganda (Ssewamala et al., 2018). Additional feedback, satisfaction, partnership quality, and product data will be gathered in Year 5 to capture qualitative experience.

Applications to Kenya
In Kenya, the in-country team is led by a group of 4 key faculty/researchers from University of Nairobi, and in partnership with representatives of Ministry of Health and Education, and NGOs. In this section, we describe the application of the SMART-Africa system strengthening framework and strategies in the Kenya context. We describe the activities, ways, and procedures that the Kenyan team applies for the capacity building.

Procedures in Applying SMART-African System Strengthening Approach.-
Given that Kenyan research investigators (from UON) already have substantial mental health epidemiological research competency and partnership experiences from prior health/mental health research capacity building projects, we structured learning opportunities specifically around child mental health, and build on the existing strengths and the Kenyan partnership team's needs (Kumar & Sensoy Bahar, 2019). Specifically, we identified areas to be focused with Kenyan team first (described next), and mapped out the activities based on Table 1 capacity building activity design framework. Table 2 (the second right column) lists the capacity building activities that have been or will be conducted in Kenya.
Capacity building activities identified to be focused on for Kenyan team include : i) developing and managing a new policy-academic-NGO-community multi-stakeholder partnership that engage stakeholders from government (MOE, MOH), research, NGOs (Basic Needs, World Vision), schools (teachers, head teachers), and communities (children and families) for child mental health policy and service research discussion; which would be an extension of prior broader mental health research network/collaboration; ii) implementation science methodology learning and applications to child mental health (including frameworks, methods for developing multi-level implementation strategies, methods for EBI content and procedure adaptation/ modification to fit local contexts/resources/needs; implementation-effectiveness evaluation design/frameworks); iii) developing an implementation collaboration structure (e.g., multi-team implementation research structure, task-sharing approach of implementation practice-research collaboration between UON and NGO Basic Needs) to effectively conducting and managing multi-components of implementation research projects; iv) new child mental health service and implementation research projects development (based on interests expressed by partnering stakeholders and researchers, e.g., around adolescent mental health, mhGap and mHealth in child mental health); v) child mental health resource development, testing, and sharing (e.g., mental health awareness materials; screening/assessment tools) that can be used broadly used in diverse Kenya contexts; and vi) strategies to strengthening school mental health evidence and service research to support school mental health policy decision and program design.
As described in Table 2, most system capacity building activities were conducted in grouptraining format and carried out during the SMART-African Annual meetings that usually take-place during July or August and last for 3-4 days. After attending the training and learning new knowledge, the research leadership team would conduct additional activities/ meetings in their own country to share knowledge and lessons learned with the in-country partnering stakeholders (with or without the support from the SMART-administrative core). For implementation research capacity building activities (hands-on experience), the Kenyan team was focused on need/implementation context assessment in Year 1, content adaptations and refinement (for community health worker training manual, family group manual; procedure) in Year 2 and 3, research and implementation team training in Year 3, and effectiveness-implementation study in Year 4. As part of the implementation research activities, Kenyan team has developed an adapted version of MFG, which has been named Familia Pamoja in Swahili and Families Together in English. The MFG implementation and evaluation research is ongoing. Table 2 lists the capacity building activities that have been conducted in Kenya. Most activities were consistent with the activities outlined in the protocol and needs. Table 2 results support some feasibility in applying the SMART-Africa Protocol. The impact evaluation in Year 5 will further assess the feasibility, quality, acceptability, and usability of the SMART-Africa approach. Table 2 right column, we describe the sources of data that have been collected/ documented by Kenyan research team. We also provide preliminary usability information based on the activities and milestones that have been achieved. SMART-Africa is in its 4 th Year of research. The Kenyan team has prioritized a few areas of capacity building activities listed in Table 2 for the remaining funding period.

•
Completing MFG Effectiveness-Implementation Research Activities and Evaluation Study. The Kenyan team is now focusing on Stage 2 capacity building activities by carrying out a MFG effectiveness-implementation study. We plan to complete the post MFG evaluation data collection, data analysis, and disseminate the findings in 2021.
• Policy-academic-NGO-community multi-stakeholder partnership and stakeholder engagement. This paper is the first step towards establishing a SMART-Africa Kenya conceptual and working model. We intend to invite stakeholder participation in refining the system strengthening conceptual model so that different technical working groups of the Ministries of Health, Education and Social Services can benefit from multi-sectoral partnerships on child mental health issues using a model sensitive to Kenyan's needs.
• Further strengthening inter-ministerial collaboration on child mental health. The Kenyan Ministry of Health is in principle meant to provide technical support on mental health including child and adolescent mental health to other relevant Ministries including Education. There are few entry points around mental health and the programming remains regimented towards integrated special needs pupils -those experiencing developmental and neurocognitive disabilities. We plan to work collaboratively with the Ministries to build on each other's capacities, train in child mental health issues and integrate EBIs like Familia Pamoja into their work.
• Developing psychoeducational materials for later dissemination. The team has developed psychoeducational materials with a view to strengthening the existing gaps through the use of simplified information sheets in control schools and community settings. These materials were developed by clinical psychology students under guidance from the team and proofread by psychiatrists, senior MOH and MOE program officers and teachers, and materials are ready for broader dissemination in Kenya.
• Engaging Basic Needs (the partnering NGO) on disseminating Familia Pamoja.
The involvement of Basic Needs on MFG implementation and co-leading the implementation-effectiveness research is a strategic part of capacity building of SMART Kenya and the consortium as such. Basic Needs will also be playing an instrumental role in the future scale up of the MFG model.
In addition to completing the activities, the Kenyan team is planning to gather additional feedback/satisfaction, acceptability, usefulness, partnership quality, and impact data (academic, mental health service, and policy accomplishments/products from the SMART-Africa) from participating stakeholders (researchers, NGOs, governmental partners) in Year 5 to provide overall progress and lessons learned to inform future child and mental health implementation research. There are also a few activities have been identified to continue after the project end.
• Additional implementation focuses on testing Familia Pamoja. As this work develops further, the in-country team is also looking to explore and agree on gaps in mental health policy in Kenya and identify points of entry to strengthen Kenyan child mental health policy. In this work, the Kenyan Ministry of Health is very supportive. By utilizing expertise of the consortium, the effort is to produce epidemiological and policy relevant data that can provide pointers to sharpening guidelines and assessments for Kenyan children in school, home and community settings. Another element of this work is to explore and agree on appropriate interventions for Kenya's school-based mental health system and the team is looking at different ways of bolstering multi-stakeholder foci (Mbwayo, Mathai, Khasakhala, et al., 2019).

•
Developing additional referral resources and pathways for high need families.
The Kenyan mental health collaboration team is considering development of ways of addressing referral pathways when any distressed pupil is identified. A Standard Operating Principles (SOPs) handbook will be specifically developed to provide local and credible referrals.
• Translating and adapting the manual. The Kenyan team intends to contextualize the manual and adapt it further by making amendments to Kiswahili, use of culturally specific terms, formatting that is user friendly and activities responsive to parent-child working together in groups.

•
Further developing implementation strategies. We plan to compile lessons learned from stakeholders and MFG implementers and users, and developing additional implementation strategies for consideration in future MFG or schoolbased mental health service and implementation research.

CONCLUSION
This paper describes the applications of the child mental health system and implementation research capacity building framework developed by the SMART-African Center and implemented in the Kenyan contexts. As illustrated in the paper, we show some feasibility of applying this framework in one of the three SMART-Africa partnering countries. In addition, our mental health landscape and resource mapping in Kenya also illustrated that capacity building in SSA countries involved complex dynamic, history, and some overlap efforts with multiple partnerships, and these are critical to consider in training activity and evaluation design. For example, in the landscape/system context analysis, we illustrated that many Kenyan researchers have involved in global research capacity-building efforts and have gained solid mental health research competency/capacity that can be transferred to child mental health implementation research. Overlook these strengths and existing capacity building efforts may hinder the development of effective North-South research partnership. Our paper also illustrates that multiple research capacity-building and collaboration efforts are occurring concurrently in Kenya, which may pose challenges in evaluating impacts of the capacity building efforts. We plan to apply qualitative data collection method to unpack how the dynamic and history influence SMART-Africa US-Kenya partnership, and better understand what the unique contribution that SMART-Africa contributes to child mental health system and implementation research in Kenya.
Although this study did not provide descriptions for applying the framework to other SMART-Africa partnering countries (in Uganda and Ghana), we anticipate the applicability of the framework ( Figure 1) and design (Table 1) to these two SSA countries may be similar, especially in ways of structuring/designing activities. Our statement is based on similar child mental health service and research context, and feedback that we learned from cross-site partnership meetings. We plan to discuss our experience with other partnering countries to share lessons learned.
